OBJECTIVES: Verification whether social implications were considered in HTA process in Poland and the UK. METHODS: The comparative analysis included following stages: 1) HTA recommendations issued in the period of January 2010 to May 2011 for AHTAPol and September 2010 to May 2011 for NICE; 2) HTA recommendations were labeled as positive, negative or other (when outcome was neither positive nor negative); 3) Check-list was composed on the basis of INAHTA definition of social issues in HTA and also of a definition which additionally introduced changes in equity and access as a social effect of implementation of a technology. Social issues were grouped in 6 categories; and 4) The impact of consideration of social implications in HTA recommendations was determined. RESULTS: Total of 132 AHTAPol Recommendations and 13 NICE Technology Appraisals issued in 2010 were reviewed (in 2 cases, because of the lack of evidence, NICE was unable to make a recommendation). Social implications were found in respectively: 27% and 82% of recommendations. The impact of social implications on HTA recommendations was more  common in the UK. In total 59 and 12 were reviewed for AHTAPoL and NICE, social implications were found in respectively: 46% and 83% of recommendations. The impact of social implications on HTA recommendations was more common in the UK. Social implications, frequently raised by AHTAPol during the analyzed period, were: changes in access to health care (48%), influence on patient’s functioning in society (15%), patient’s ability to work (14%) and others (21% - mainly, avoidable hospitalization). NICE paid more attention to: changes in access to health care (26%), influence on patient’s functioning in society (15%), influence on subcultures (15%) and others (35% - mainly, discrimination). CONCLUSIONS: During the analyzed period, NICE considered social implications more frequently than AHTAPol.  NICE and AHTAPol paid attention to different types of social implications.
